The International Space Station and Venus, 19-28 November 2013

The ISS passes almost on top of Venus  as seen from Adelaide on the evening of Friday November 22 at 22:22 ACDST.

During this week there are a series of bright evening passes of the International Space Station. For many places in Australia the ISS comes close to Venus. In some places the ISS almost appears to go over the top of Venus, for example 22 November at 22:22 ACDST in Adelaide and 24 November 21:18 AEDST in Sydney.

When and what you will see is VERY location dependent, so you need to use either Heavens Above or CalSky to get site specific predictions for your location. Even the difference between the city centre and the suburbs can mean the difference between seeing the ISS go over Venus or just below it.

Start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, on the night there may be slight differences in the time of the  ISS appearing due to orbit changes not picked up by the predictions. The ISS will be moving reasonably fast when it passes Venus, so be alert.

If you are trying to take pictures, make sure you have a tripod and have the camera in night mode (or a mode were you can take exposures of around 5 minutes), if you can set the camera to take multiple exposures unattended that would be best.

I'm going to attempt to photograph from jjust south of the city. Hopefully clouds stay where they are. If I'm succesful I'll send you the pictures.
 
I had clouds over Venus at the critical moments. got a shot of the ISS exiting the cloud afterwards :-(
